Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2017020382
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine which can accurately determine that actual measurement data of MFB are affected by an influence of noise, and can perform engine control based on a specific ratio combustion point accompanied by a proper noise countermeasure by using a determination result.SOLUTION: Actual measurement data of MFB at crank angle synchronization based on in-cylinder pressure which is detected by an in-cylinder pressure sensor 30 are calculated. SA-CA10 feedback control and CA50 feedback control based on actual measurement CA10 and actual measurement CA50 which are calculated on the basis of the actual measurement data are performed. A first correlation index value α related to the MFB and a second correlation index value β related to dMFB/d θ are calculated. When the first correlation index value α is smaller than a first determination value α, and the second correlation index value β is not smaller than a second determination value β, the feedback control is stopped.SELECTED DRAWING: Figure 8
